A patient presents with redness, pain, and photophobia in the left eye. Slit-lamp examination reveals ciliary injection, corneal edema, and a mid-dilated pupil with fixed reaction to light. Which of the following conditions is most likely responsible for this presentation?

Correct Answer: A

Rationale: The presentation described in the question is classic for anterior uveitis. Anterior uveitis is an inflammatory condition affecting the iris and ciliary body and is characterized by redness, pain, and photophobia. Slit-lamp examination typically reveals ciliary injection (redness around the iris), corneal edema, and a mid-dilated pupil with a fixed reaction to light due to inflammation causing spasm of the iris muscles. Acute angle-closure glaucoma would present with similar symptoms but would also have increased intraocular pressure, which is not mentioned in the presentation. Endophthalmitis is an infection of the intraocular cavities and would typically present with more severe symptoms, such as severe pain, vision loss, and presence of pus in the eye. Corneal abrasion would present with pain, foreign body sensation, and possibly tearing but would not cause ciliary injection or fixed pupil reaction as

Correct Answer: A

Rationale: The nurse sharing Mr. Steve's medical records with a group of visiting members of a medical mission team violates his right to expect that all communications and records pertaining to his care should be treated as confidential. Patient confidentiality is a fundamental ethical principle in healthcare that protects a patient's privacy and sensitive information. Sharing medical records without the patient's consent breaches this confidentiality and can lead to legal and ethical consequences. It is important for healthcare providers to maintain the confidentiality of patient information to uphold trust between patients and healthcare professionals.

Correct Answer: B

Rationale: The most critical action to prioritize for ensuring patient safety during a cardiopulmonary exercise stress test is to monitor the patient's electrocardiogram (ECG) rhythm continuously during the test (Option B). This monitoring allows the healthcare team to promptly detect any abnormal heart rhythms or signs of cardiac distress, enabling timely intervention if necessary. Continuous ECG monitoring is essential during exercise testing as it helps in assessing the heart's response to physical activity and identifying any potential cardiac abnormalities or complications that may arise during the test. By closely monitoring the ECG rhythm, the nurse can ensure the patient's safety and well-being throughout the procedure. Administering a beta-blocker medication before the test (Option A) may be indicated in some cases but is not as crucial as continuous ECG monitoring during the test. Encouraging the patient to consume a heavy meal before the test (Option C) is contraindicated as it can interfere with the accuracy of the results

Correct Answer: A

Rationale: Having a tracheostomy means that a patient has an artificial opening in their neck to help them breathe. Therefore, any issues related to breathing, such as blockages in the tracheostomy tube or difficulty in clearing secretions, can pose a major problem for a patient with a tracheostomy. It is crucial to monitor the patient's respiratory status closely and intervene promptly if any breathing difficulties arise to prevent potential respiratory distress or complications.

Correct Answer: D

Rationale: The correct advice to give to the owner of the dog in case of a dog bite is to feed the dog well and observe its behavior closely. It is not necessary to give away, impound, or kill the dog immediately after a bite incident. By feeding the dog well and observing its behavior, the owner can see if there are any underlying issues that may have caused the dog to bite. Additionally, observing the dog can help the owner determine if the dog has any health issues that need to be addressed. This approach allows the owner to make an informed decision about the dog's future while ensuring the safety of others.

Correct Answer: A

Rationale: The first priority for a nurse caring for a patient experiencing a seizure is safety. Ensuring the safety of the patient is crucial to prevent injury during the seizure episode. This includes clearing the area around the patient of any harmful objects, preventing the patient from falling or hitting their head, placing them in a safe position to prevent aspiration if they vomit, and staying with the patient until the seizure ends. Once the patient is safe, the nurse can then focus on other aspects of care such as assessing airway, providing emotional support, and monitoring for complications.

Correct Answer: C

Rationale: An amniotic fluid embolism is a rare and life-threatening complication during labor and delivery. It occurs when amniotic fluid or fetal cells enter the maternal circulation, triggering a rapid immune response that can lead to cardiovascular collapse and respiratory failure. The priority nursing intervention for a woman in active labor diagnosed with an amniotic fluid embolism is to initiate cardiopulmonary resuscitation (CPR) to support her vital functions and circulation. Providing immediate CPR can help sustain her until further medical interventions can be implemented. Administering oxygen and preparing for a cesarean section may be necessary but should occur after CPR is initiated to stabilize the woman's condition. Inserting an indwelling urinary catheter is not the priority in this emergency situation, as maintaining adequate cardiac and respiratory function takes precedence.

Correct Answer: D

Rationale: Insulinoma is a rare neuroendocrine tumor that arises from pancreatic beta cells, leading to excessive production and secretion of insulin. The symptoms described in the patient, such as weight loss, fatigue, nausea, vomiting, abdominal pain, hypoglycemia, and elevated insulin levels, are characteristic of insulinoma.

Correct Answer: A

Rationale: The described presentation of a pruritic, annular rash with central clearing and a raised, scaly border that spreads outward in a centrifugal pattern is characteristic of tinea corporis, commonly known as ringworm. This fungal infection affects the skin and is typically ring-shaped, with a well-defined, slightly raised, and scaly border. The central area often clears as the lesion enlarges peripherally, resembling a ring. It is important to note that ringworm is not caused by a worm but by a fungus. Treatment typically involves antifungal medications applied topically or taken orally, depending on the severity of the infection.
